GIS Data: US Data

Access geospatial information from a variety of sources. You will need to use search facets to find specific GIS file types.

Access geospatial information from Federal agencies and a growing number of state, local, tribal and private agencies. Create a login and password for yourself to access the system. Access point to U.S. Federal Executive Branch datasets. Note that data is grouped in three ways: The "Raw" data catalog allows limiting by .shp or .kml formats. Tools Catalog leads to agency tools or agency web pages that allow you to mine data sets. Geodata catalog has miscellaneous geo-referenced data.
